FIG. 1 is a view illustrating an integrated intelligence system according to an embodiment of the disclosure.

Referring to FIG. 1, an integrated intelligence system 10 may include a user terminal 100, an intelligent server 200, a personal information server 300, or a proposal server 400.

The user terminal 100 may provide services necessary for the user through an app (or application program) (e.g., an alarm app, message app, photo (gallery) app, etc.) stored in the user terminal 100. For example, the user terminal 100 may execute and operate another app through an intelligent app (or speech recognition app) stored in the user terminal 100. The intelligent app of the user terminal 100 may receive user inputs to execute and operate the other app through the intelligent app. The user inputs may be received through, e.g., a physical button, touchpad, speech input, or remote input. According to an embodiment of the disclosure, the user terminal 100 may be various terminal devices (or electronic devices) connectable to the internet, such as a cellular phone, smartphone, PDA, or laptop computer.

According to an embodiment of the disclosure, the user terminal 100 may receive an utterance as a user input. The user terminal 100 may receive the utterance and generate a command to operate the app based on the utterance. Accordingly, the user terminal 100 may operate the app using the command.

The intelligent server 200 may receive the user's speech input from the user terminal 100 through a communication network and convert the speech input into text data. According to an embodiment of the disclosure, the intelligent server 200 may generate (or select) a path rule based on the text data. The path rule may include information about actions (or operations) to perform the functions of the app or information about parameters necessary to execute the operations. Further, the path rule may include the order of the operations of the app. The user terminal 100 may receive the path rule, select an app according to the path rule, and execute the operations included in the path rule on the selected app.

As used herein, the term “path rule” may generally mean a sequence of states for the electronic device to perform a task requested by the user, but not limited thereto. In other words, the path rule may contain information about a sequence. The task may be a certain action that, e.g., an intelligent app may provide. The task may include producing a schedule, transmitting a photo to a desired party, or providing weather information. The user terminal 100 may perform the task by sequentially having at least one or more states (e.g., operation states of the user terminal 100).

According to an embodiment, the path rule may be provided or created by an artificial intelligence (AI) system. The AI system may be a rule-based system or a neural network-based system (e.g., feedforward neural network (FNN)) or recurrent neutral network (RNN)). Or, the AI system may be a combination thereof or a system different therefrom. According to an embodiment, the path rule may be selected from a set of pre-defined path rules or created in real-time in response to a user request. For example, the AI system may select at least one among a plurality of pre-defined path rules or may dynamically (or real-time) create a path rule. The user terminal 100 may use a hybrid system to provide the path rule.

According to an embodiment, the user terminal 100 may execute the operation and display, on the display, the screen corresponding to the state of the user terminal 100 having performed the operation. As another example, the user terminal 100 may execute the operation and abstain from displaying the results of performing the operation on the display. The user terminal 100 may execute, e.g., a plurality of operations and display, on the display, only some results of the plurality of operations. The user terminal 100 may display, on the display, e.g., the results of executing only the last operation in order. As another example, the user terminal 100 may receive a user input and display the results of executing the operation on the display.

The personal information server 300 may include a database storing user information. For example, the personal information server 300 may receive user information (e.g., context information or app execution) from the user terminal 100 and store the user information in the database. The intelligent server 200 may receive the user information from the personal information server 300 through the communication network and use the same in creating a path rule for user inputs. According to an embodiment of the disclosure, the user terminal 100 may receive user information from the personal information server 300 through the communication network and use the same as information for managing the database.

The proposal server 400 may include a database that stores information about functions to be provided or introductions of applications or functions in the terminal. For example, the proposal server 400 may receive user information of the user terminal 100 from the personal information server 300 and include a database for functions that the user may use. The user terminal 100 may receive information about functions to be provided from the proposal server 400 through the communication network and provide the information to the user.

FIG. 2 is a block diagram illustrating a user terminal in an integrated intelligence system according to an embodiment of the disclosure.

Referring to FIG. 2, the user terminal 100 may include an input module 110, a display 120, a speaker 130, a memory 140, and a processor 150. The user terminal 100 may further include a housing. The components of the user terminal 100 may be positioned in or on the housing. The user terminal 100 may further include a communication circuit positioned inside the housing. The user terminal 100 may transmit or receive data (or information) to/from an external server (e.g., the intelligent server 200) through the communication circuit.

According to an embodiment of the disclosure, the input module 110 may receive user inputs from the user. For example, the input module 110 may receive a user input from an external device (e.g., a keyboard or headset) connected thereto. As another example, the input module 110 may include a touchscreen combined with the display 120 (e.g., a touchscreen display). As another example, the input module 110 may include a hardware key (or a physical key) 112 positioned in the user terminal 100 (or the housing of the user terminal 100).

According to an embodiment, the input module 110 may include a microphone capable of receiving utterances as speech signals. For example, the input module 110 may include a speech input system and receive utterances as speech signals through the speech input system. The microphone may be exposed through, e.g., a portion (e.g., a first portion) of the housing.

According to an embodiment of the disclosure, the display 120 may display images, videos, and/or application execution screens. For example, the display 120 may display a graphical user interface (GUI) of the app. According to an embodiment, the display 120 may be exposed through, e.g., a portion (e.g., a second portion) of the housing.

According to an embodiment of the disclosure, the speaker 130 may output speech signals. For example, the speaker 130 may output speech signals generated from inside the user terminal 100 to the outside. According to an embodiment, the speaker 130 may be exposed through, e.g., a portion (e.g., a third portion) of the housing.

According to an embodiment of the disclosure, the memory 140 may store a plurality of apps 141 and 143. The plurality of apps 141 and 143 may be, e.g., programs for performing a function corresponding to a user input. According to an embodiment of the disclosure, the memory 140 may include the intelligent agent 145, the execution manager module 147, or the intelligent service module 149. The intelligent agent 145, the execution manager module 147, and the intelligent service module 149 may be frameworks (or application frameworks) to process received user inputs (e.g., utterances).

According to an embodiment of the disclosure, the memory 140 may include a database that may store information necessary to recognize user inputs. For example, the memory 140 may include a log database capable of storing log information. As another example, the memory 140 may include a persona database capable of storing user information.

According to an embodiment of the disclosure, the memory 140 may store the plurality of apps 141 and 143. The plurality of apps 141 and 143 may be loaded and operated. For example, the plurality of apps 141 and 143 stored in the memory 140 may be loaded and operated by the execution manager module 147. The plurality of apps 141 and 143 may include execution service modules 141 a and 143 a to perform functions. According to an embodiment, the plurality of apps 141 and 143 may execute a plurality of operations (e.g., a sequence of states) 141 b and 143 b through the execution service modules 141 a and 143 a to perform functions. In other words, the execution service modules 141 a and 143 a may be activated by the execution manager module 147 and execute the plurality of operations 141 b and 143 b.

According to an embodiment of the disclosure, when the operations 141 b and 143 b of the apps 141 and 143 are executed, the execution state screens as per the execution of the operations 141 b and 143 b may be displayed on the display 120. The execution state screens may be screens, e.g., in the state of the operations 141 b and 143 b having been completed. The execution state screens may be screens, e.g., in the state of the execution of the operations 141 b and 143 b having been stopped (partial landing) (e.g., when parameters required for the operations 141 b and 143 b are not inputted).

According to an embodiment of the disclosure, the execution service modules 141 a and 143 a may execute the operations 141 b and 143 b as per a path rule. For example, the execution service modules 141 a and 143 a may be activated by the execution manager module 147, receive an execution request as per the path rule from the execution manager module 147, and execute the operations 141 b and 143 b according to the execution request, thereby executing the functions of the apps 141 and 143. The execution service modules 141 a and 143 a may send completion information to the execution manager module 147 when the execution of the operations 141 b and 143 b is complete.

According to an embodiment of the disclosure, when the plurality of operations 141 b and 143 b are executed on the apps 141 and 143, the plurality of operations 141 b and 143 b may sequentially be executed. When the execution of one operation (e.g., operation 1 of the first app 141 or operation 1 of the second app 143) is complete, the execution service modules 141 a and 143 a may open the subsequent operation (e.g., operation 2 of the first app 141 or operation 2 of the second app 143) and send completion information to the execution manager module 147. Here, ‘open an operation’ may be appreciated as transitioning the operation into an executable state or preparing for the execution of the operation. In other words, unless the operation is open, the operation cannot be executed. Upon receiving the completion information, the execution manager module 147 may transfer an execution request for the subsequent operation (e.g., operation 2 of the first app 141 or operation 2 of the second app 143) to the execution service module. According to an embodiment of the disclosure, when the plurality of apps 141 and 143 are executed, the plurality of apps 141 and 143 may sequentially be executed. For example, when the execution of the last operation of the first app 141 (e.g., operation 3 of the first app 141) is complete, and completion information is thus received, the execution manager module 147 may send an execution request for the first operation of the second app 143 (e.g., operation 1 of the second app 143) to the execution service module 143 a.

According to an embodiment of the disclosure, when the plurality of operations 141 b and 143 b are executed on the apps 141 and 143, the resultant screens of execution of the plurality of operations 141 b and 143 b may be displayed on the display 120. According to an embodiment of the disclosure, only some of the plurality of resultant screens of execution of the plurality of operations 141 b and 143 b may be displayed on the display 120.

According to an embodiment of the disclosure, the memory 140 may store an intelligent app (e.g., a speech recognition app) interworking with the intelligent agent 145. The app interworking with the intelligent agent 145 may receive an utterance as a speech signal and process the same. According to an embodiment of the disclosure, the app interworking with the intelligent agent 145 may be operated by particular inputs entered through the input module 110 (e.g., inputs through the hardware key or touchscreen, or particular speech inputs).

According to an embodiment of the disclosure, the intelligent agent 145, the execution manager module 147, or the intelligent service module 149 stored in the memory 140 may be executed by the processor 150. The functions of the intelligent agent 145, the execution manager module 147, or the intelligent service module 149 may be implemented by the processor 150. The functions of the intelligent agent 145, the execution manager module 147, and the intelligent service module 149 are described in connection with operations of the processor 150. According to an embodiment of the disclosure, the intelligent agent 145, the execution manager module 147, or the intelligent service module 149 stored in the memory 140 may be implemented in software or hardware.

According to an embodiment of the disclosure, the processor 150 may control the overall operation of the user terminal 100. For example, the processor 150 may control the input module 110 to receive user inputs. The processor 150 may control the display 120 to display images. The processor 150 may control the speaker 130 to output speech signals. The processor 150 may control the memory 140 to execute programs and fetch or store necessary information.

According to an embodiment of the disclosure, the processor 150 may execute the intelligent agent 145, the execution manager module 147, or the intelligent service module 149 stored in the memory 140. Thus, the processor 150 may implement the function of the intelligent agent 145, the execution manager module 147, or the intelligent service module 149.

According to an embodiment of the disclosure, the processor 150 may execute the intelligent agent 145 to generate commands to operate apps based on speech signals received as user inputs. According to an embodiment of the disclosure, the processor 150 may execute the execution manager module 147 to execute the apps 141 and 143 stored in the memory 140 as per the commands generated. According to an embodiment, the processor 150 may execute the intelligent service module 149 to manage the user information and process user inputs using the user information.

The processor 150 may execute the intelligent agent 145 to send user inputs received through the input module 110 to the intelligent server 200 and process the user inputs through the intelligent server 200.

According to an embodiment of the disclosure, the processor 150 may execute the intelligent agent 145 to pre-process the user inputs before sending the user inputs to the intelligent server 200. According to an embodiment of the disclosure, the intelligent agent 145 may include an adaptive echo canceller (AEC) module, a noise suppression (NS) module, an end-point detection (EPD) module, or an automatic gain control (AGC) module to pre-process the user inputs. The AEC module may remove echoes mixed in the user inputs. The NS module may suppress background noise mixed in the user inputs. The EPD module may detect end points of user speech contained in the user inputs to find where the user speech is present using the detected end points. The AGC module may recognize the user inputs and adjust the volume of the user inputs for a proper processing of the recognized user inputs. According to an embodiment of the disclosure, although able to execute all of the pre-processing components described above to provide a better performance, the processor 150 may alternatively execute some of the pre-processing components to be operated at reduced power.

According to an embodiment of the disclosure, the intelligent agent 145 may include a wake-up recognition module stored in the memory 140 to recognize the invocation. Thus, the processor 150 may recognize the wake-up command through the wake-up recognition module, and upon receiving the wake-up command, the processor 150 may execute the intelligent agent 145 to receive user inputs. The wake-up recognition module may be implemented in a low-power processor (e.g., a processor included in an audio codec). According to an embodiment, the processor 150 may execute the intelligent agent 145 upon receiving a user input through the hardware key. When the intelligent agent 145 is executed, an intelligent app (e.g., a speech recognition app) interworking with the intelligent agent 145 may be executed.

According to an embodiment of the disclosure, the intelligent agent 145 may include a speech recognition module to execute user inputs. The processor 150 may receive user inputs to execute operations on the app through the speech recognition module. For example, the processor 150 may recognize, through the speech recognition module, limited user (speech) inputs (e.g., the “click” sound made when the capturing operation is executed on the camera app) for executing operations, such as the wake-up command on the apps 141 and 143. The processor 150 may assist the intelligent server 200 to recognize and quickly process user commands, which are processable in the user terminal 100, through the speech recognition module. According to an embodiment, the speech recognition module of the intelligent agent 145 to execute user inputs may be implemented in an app processor.

According to an embodiment of the disclosure, the speech recognition module (including the speech recognition module of the wake-up recognition module) of the intelligent agent 145 may recognize user inputs using an algorithm for recognizing speech. The algorithm used to recognize speech may be at least one of, e.g., a hidden Markov model (HMM) algorithm, an artificial neural network (ANN) algorithm, or a dynamic time warping (DTW) algorithm.

According to an embodiment of the disclosure, the processor 150 may execute the intelligent agent 145 to convert the speech inputs into text data. For example, the processor 150 may send a user speech through the intelligent agent 145 to the intelligent server 200 and receive text data corresponding to the user speech from the intelligent server 200. Thus, the processor 150 may display the converted text data on the display 120.

According to an embodiment of the disclosure, the processor 150 may execute the intelligent agent 145 to receive a path rule from the intelligent server 200. According to an embodiment, the processor 150 may transfer the path rule to the execution manager module 147 through the intelligent agent 145.

According to an embodiment of the disclosure, the processor 150 may execute the intelligent agent 145 to transfer an execution result log as per the path rule received from the intelligent server 200 to the intelligent service module 149. The execution result log transferred may be accrued and managed in user preference information of a persona module 149 b.

According to an embodiment of the disclosure, the processor 150 may execute the execution manager module 147 to receive the path rule from the intelligent agent 145, execute the apps 141 and 143, and allow the apps 141 and 143 to execute the operations 141 b and 143 b contained in the path rule. For example, the processor 150 may send command information (e.g., path rule information) to execute the operations 141 b and 143 b to the apps 141 and 143 through the execution manager module 147 and receive completion information about the operations 141 b and 143 b from the apps 141 and 143.

According to an embodiment of the disclosure, the processor 150 may execute the execution manager module 147 to transfer command information (e.g., path rule information) to execute the operations 141 b and 143 b of the apps 141 and 143 between the intelligent agent 145 and the apps 141 and 143. The processor 150 may bind the apps 141 and 143 to be executed as per the path rule through the execution manager module 147 and transfer the command information (e.g., path rule information) about the operations 141 b and 143 b contained in the path rule to the apps 141 and 143. For example, the processor 150 may sequentially transfer the operations 141 b and 143 b contained in the path rule to the apps 141 and 143 through the execution manager module 147, sequentially executing the operations 141 b and 143 b of the apps 141 and 143 as per the path rule.

According to an embodiment, the processor 150 may execute the execution manager module 147 to manage the execution states of the operations 141 b and 143 b of the apps 141 and 143. For example, the processor 150 may receive information about the execution states of the operations 141 b and 143 b from the apps 141 and 143 through the execution manager module 147. When the execution states of the operations 141 b and 143 b are, e.g., partial landing states (e.g., when no parameters required for the operations 141 b and 143 b are entered), the processor 150 may transfer information about the partial landing states to the intelligent agent 145 through the execution manager module 147. The processor 150 may request the user to enter necessary information (e.g., parameter information) using the information transferred through the intelligent agent 145. When the execution states of the operations 141 b and 143 b are other states, e.g., operation states, the processor 150 may receive an utterance from the user through the intelligent agent 145. The processor 150 may transfer information about the apps 141 and 143 being executed through the execution manager module 147 and the execution states of the apps 141 and 143 to the intelligent agent 145. The processor 150 may send the utterance through the intelligent agent 145 to the intelligent server 200. The processor 150 may receive parameter information about the utterance from the intelligent server 200 through the intelligent agent 145. The processor 150 may transfer the parameter information received through the intelligent agent 145 to the execution manager module 147. The execution manager module 147 may change the parameters of the operations 141 b and 143 b into new parameters using the received parameter information.

According to an embodiment, the processor 150 may execute the execution manager module 147 to transfer the parameter information contained in the path rule to the apps 141 and 143. When the plurality of apps 141 and 143 are sequentially executed as per the path rule, the execution manager module 147 may deliver the parameter information contained in the path rule from one app to the other.

According to an embodiment of the disclosure, the processor 150 may execute the execution manager module 147 to receive a plurality of path rules. The processor 150 may select a plurality of path rules based on the utterance through the execution manager module 147. For example, when a utterance specifies a certain app 141 to execute some operation 141 a but does not specify another app 143 to execute the other operation 143 b, the processor 150 may, through the execution manager module 147, receive a plurality of different path rules by which the same app 141 (e.g., a gallery app) to execute the operation 141 a is executed and a different app 143 (e.g., a message app or a telegram app) to execute the other operation 143 b is executed. The processor 150 may execute the same operations 141 b and 143 b (e.g., the same continuous operations 141 b and 143 b) of the plurality of path rules through the execution manager module 147. When the same operations have been executed, the processor 150 may, through the execution manager module 147, display, on the display 120, the state screen where the different apps 141 and 143 each contained in a respective one of the plurality of path rules may be selected.

According to an embodiment of the disclosure, the intelligent service module 149 may include a context module 149 a, a persona module 149 b, or a proposal module 149 c.

The processor 150 may execute the context module 149 a to identify current states of the apps 141 and 143 from the apps 141 and 143. For example, the processor 150 may execute the context module 149 a to receive context information indicating the current states of the apps 141 and 143 to identify the current states of the apps 141 and 143 through the received context information.

The processor 150 may execute the persona module 149 b to manage the personal information about the user using of the user terminal 100. For example, the processor 150 may execute the persona module 149 b to identify use information and execution results of the user terminal 100 and manage the user's personal information using the identified use information and execution results of the user terminal 100.

The processor 150 may execute the proposal module 149 c to predict the user's intention and recommend a command for the user based on the user's intention. For example, the processor 150 may execute the proposal module 149 c to recommend a command for the user given the user's current state (e.g., time, place, context, or app).

According to an embodiment, a system 10 comprises a first electronic device (e.g., the user terminal 100) including a communication circuit, an input module 110 (e.g., a microphone and a speaker), at least one processor (e.g., the processor 150) being part of the first electronic device or configured to remotely communicate with the first electronic device, and a memory 140 positioned on or outside the first electronic device and operatively connected with the at least one processor, wherein the memory may store instructions executed to enable the at least one processor to configured to perform a first operation, receive a utterance through the microphone while performing the first operation, the utterance including only at least one selected wake-up word used to invoke a speech-based intelligent service, identify a response related to the first operation, and provide the response through the speaker.

According to an embodiment, the instructions may be configured to enable the first processor to receive a user input for the response, identify a second operation related to the first operation when the received user input corresponds to a designated input, and further output a second response to identify whether to perform the second operation.

According to an embodiment, the instructions may be configured to enable the first processor to receive a user input for the response and when the received user input does not correspond to a designated input, perform at least one function corresponding to the first operation.

According to an embodiment, the instructions may be configured to enable the first processor to transmit data related to the first operation to the server when no additional utterance is received within a designated time after the utterance is received.

According to an embodiment, the instructions may be configured to enable the at least one processor to identify whether the first electronic device is operated in a designated mode and, after receiving the utterance, transmit data related to the first operation to the server. For example, the designated mode may include a mode (eyes-free mode) in which the user terminal 100 recognizes the user's biometric information and the user does not look at the user terminal 100 or is a designated distance away or a hold mode in which the screen (e.g., the display device 160) of the user terminal 100 is turned off as no user input is identified for a designated time.

FIG. 3 is a view illustrating an example of executing an intelligent app on a user terminal according to an embodiment of the disclosure.

FIG. 3 illustrates an example in which the user terminal 100 receives user inputs and executes an intelligent app (e.g., a speech recognition app) interworking with the intelligent agent 145.

Referring to FIG. 3, according to an embodiment of the disclosure, the user terminal 100 may execute an intelligent app to recognize speech through the hardware key 112. For example, when the user terminal 100 receives user inputs through the hardware key 112, the user terminal 100 may display a user interface (UI) 121 of the intelligent app on the display 120. The user may touch a speech recognition button 121 a in the UI 121 of the intelligent app for speech entry 120 b with the intelligent app UI 121 displayed on the display 120. As another example, the user may continuously press the hardware key 112 for speech entry 120 b.

According to an embodiment of the disclosure, the user terminal 100 may execute an intelligent app to recognize speech through the microphone 111. For example, when a designated speech (e.g., “wake up!”) is entered (120 a) through the microphone 111, the user terminal 100 may display the intelligent app UI 121 on the display 120.

FIG. 4 is a block diagram illustrating an intelligent server in an integrated intelligence system according to an embodiment of the disclosure.

Referring to FIG. 4, an intelligent server 200 may include an automatic speech recognition (ASR) module 210, a natural language understanding (NLU) module 220, a path planner module 230, a dialogue manager (DM) module 240, a natural language generator (NLG) module 250, or a text-to-speech (TTS) module 260. According to an embodiment, the intelligent server 200 may include a communication circuit, a memory, and a processor. The processor may execute commands stored in the memory to drive the ASR module 210, the NLU module 220, the path planner module 230, the DM module 240, the NLG module 250, and the TTS module 260. The intelligent server 200 may transmit or receive data (or information) to/from an external electronic device (e.g., the user terminal 100) through the communication circuit.

The NLU module 220 or the path planner module 230 of the intelligent server 200 may generate a path rule.

According to an embodiment of the disclosure, the ASR module 210 may convert user inputs received from the user terminal 100 into text data.

According to an embodiment of the disclosure, the ASR module 210 may convert user inputs received from the user terminal 100 into text data. For example, the ASR module 210 may include a speech recognition module. The speech recognition module may include an acoustic model and a language model. For example, the acoustic model may include vocalization-related information, and the language model may include unit phonemic information and combinations of pieces of unit phonemic information. The speech recognition module may convert utterances into text data using the vocalization-related information and unit phonemic information. Information about the acoustic model and the language model may be stored in, e.g., an ASR database (DB) 211.

According to an embodiment of the disclosure, the NLU module 220 may perform syntactic analysis or semantic analysis to identify the user's intent. As per the syntactic analysis, the user input may be divided into syntactic units (e.g., words, phrases, or morphemes) and what syntactic elements the syntactic units have may be identified. The semantic analysis may be performed using, e.g., semantic matching, rule matching, or formula matching. Thus, the NLU module 220 may obtain a domain, intent, or parameters (or slots) necessary to represent the intent for the user input.

According to an embodiment of the disclosure, the NLU module 220 may determine the user's intent and parameters using the matching rule which has been divided into the domain, intent, and parameters (or slots) necessary to identify the intent. For example, one domain (e.g., an alarm) may include a plurality of intents (e.g., alarm settings or releasing alarm), and one intent may include a plurality of parameters (e.g., time, repetition count, or alarm sound). The plurality of rules may include, e.g., one or more essential element parameters. The matching rule may be stored in an NLU database (DB) 221.

According to an embodiment of the disclosure, the NLU module 220 may identify the meaning of a word extracted from the user input using linguistic features (e.g., syntactic elements) such as morphemes or phrases, match the identified meaning of the word to the domain and intent, and determine the user's intent. For example, the NLU module 220 may calculate how many words extracted from the user input are included in each domain and intent to thereby determine the user's intent. According to an embodiment of the disclosure, the NLU module 220 may determine the parameters of the user input using the word which is a basis for identifying the intent. According to an embodiment of the disclosure, the NLU module 220 may determine the user's intent using the NLU DB 221 storing the linguistic features for identifying the intent of the user input. According to an embodiment of the disclosure, the NLU module 220 may determine the user's intent using a personal language model (PLM). For example, the NLU module 220 may determine the user's intent using personal information (e.g., contacts list or music list). The PLM may be stored in, e.g., the NLU DB 221. According to an embodiment of the disclosure, the ASR module 210, but not the NLU module 220 alone, may recognize the user's speech by referring to the PLM stored in the NLU DB 221.

According to an embodiment of the disclosure, the NLU module 220 may generate a path rule based on the intent of the user input and parameters. For example, the NLU module 220 may select an app to be executed based on the intent of the user input and determine operations to be performed on the selected app. The NLU module 220 may determine parameters corresponding to the determined operations to generate a path rule. According to an embodiment of the disclosure, the path rule generated by the NLU module 220 may include information about the app to be executed, operations (e.g., at least one or more states) to be executed on the app, and the parameters necessary to execute the operations.

According to an embodiment of the disclosure, the NLU module 220 may generate one or more path rules based on the parameters and intent of the user input. For example, the NLU module 220 may receive a path rule set corresponding to the user terminal 100 from the path planner module 230, map the parameters and intent of the user input to the received path rule set, and determine the path rule.

According to an embodiment of the disclosure, the NLU module 220 may determine the app to be executed, operations to be executed on the app, and parameters necessary to execute the operations based on the parameters and intent of the user input, thereby generating one or more path rules. For example, the NLU module 220 may generate a path rule by arranging the app to be executed and the operations to be executed on the app in the form of ontology or a graph model according to the user input using the information of the user terminal 100. The generated path rule may be stored through, e.g., the path planner module 230 in a path rule database (PR DB) 231. The generated path rule may be added to the path rule set of the PR DB 231.

According to an embodiment of the disclosure, the NLU module 220 may select at least one of a plurality of path rules generated. For example, the NLU module 220 may select the optimal one of the plurality of path rules. As another example, the NLU module 220 may select a plurality of path rules when only some operations are specified based on the utterance. The NLU module 220 may determine one of the plurality of path rules by the user's additional input.

According to an embodiment of the disclosure, the NLU module 220 may send the path rule to the user terminal 100 at a request for the user input. For example, the NLU module 220 may send one path rule corresponding to the user input to the user terminal 100. As another example, the NLU module 220 may send a plurality of path rules corresponding to the user input to the user terminal 100. For example, when only some operations are specified based on the utterance, the plurality of path rules may be generated by the NLU module 220.

According to an embodiment of the disclosure, the path planner module 230 may select at least one of the plurality of path rules.

According to an embodiment of the disclosure, the path planner module 230 may deliver a path rule set including the plurality of path rules to the NLU module 220. The plurality of path rules in the path rule set may be stored in the form of a table in the PR DB 231 connected with the path planner module 230. For example, the path planner module 230 may deliver a path rule set corresponding to information (e.g., operating system (OS) information or app information) of the user terminal 100 which is received from the intelligent agent 145 to the NLU module 220. The table stored in the PR DB 231 may be stored, e.g., per domain or per domain version.

According to an embodiment of the disclosure, the path planner module 230 may select one or more path rules from the path rule set and deliver the same to the NLU module 220. For example, the path planner module 230 may match the user's intent and parameters to the path rule set corresponding to the user terminal 100 to select one or more path rules and deliver them to the NLU module 220.

According to an embodiment of the disclosure, the path planner module 230 may generate one or more path rules using the user's intent and parameters. For example, the path planner module 230 may determine an app to be executed and operations to be executed on the app based on the user's intent and parameters to generate one or more path rules. According to an embodiment of the disclosure, the path planner module 230 may store the generated path rule in the PR DB 231.

According to an embodiment of the disclosure, the path planner module 230 may store the path rule generated by the NLU module 220 in the PR DB 231. The generated path rule may be added to the path rule set stored in the PR DB 231.

According to an embodiment of the disclosure, the table stored in the PR DB 231 may include a plurality of path rules or a plurality of path rule sets. The plurality of path rule or the plurality of path rule sets may reflect the kind, version, type, or characteristic of the device performing each path rule.

According to an embodiment of the disclosure, the DM module 240 may determine whether the user's intent identified by the path planner module 230 is clear. For example, the DM module 240 may determine whether the user's intent is clear based on whether parameter information is sufficient. The DM module 240 may determine whether the parameters identified by the NLU module 220 are sufficient to perform a task. According to an embodiment of the disclosure, when the user's intent is unclear, the DM module 240 may perform feedback to send a request for necessary information to the user. For example, the DM module 240 may perform feedback to send a request for parameter information to identify the user's intent.

According to an embodiment of the disclosure, the DM module 240 may include a content provider module. When the operation can be performed based on the intent and parameters identified by the NLU module 220, the content provider module may generate the results of performing the task corresponding to the user input. According to an embodiment of the disclosure, the DM module 240 may send the results generated by the content provider module to the user terminal 100 in response to the user input.

According to an embodiment of the disclosure, the NLG module 250 may convert designated information into text. The text information may be in the form of a natural language utterance. The designated information may be, e.g., information about an additional input, information indicating that the operation corresponding to the user input is complete, or information indicating the user's additional input (e.g., feedback information for the user input). The text information may be sent to the user terminal 100 and displayed on the display 120, or the text information may be sent to the TTS module 260 and converted into a speech.

According to an embodiment of the disclosure, the TTS module 260 may convert text information into speech information. The TTS module 260 may receive the text information from the NLG module 250, convert the text information into speech information, and send the speech information to the user terminal 100. The user terminal 100 may output the speech information through the speaker 130.

According to an embodiment of the disclosure, the NLU module 220, the path planner module 230, and the DM module 240 may be implemented in a single module. For example, the NLU module 220, the path planner module 230, and the DM module 240 may be implemented in a single module to determine the user's intent and parameters and to generate a response (e.g., a path rule) corresponding to the user's intent and parameters determined. Accordingly, the generated response may be transmitted to the user terminal 100.

FIG. 5 is a view illustrating an example of identifying current states by a context module of an intelligent service module according to an embodiment of the disclosure.

Referring to FIG. 5, upon receiving (1) a context request from the intelligent agent 145, the processor 150 may send a request (2) for context information indicating the current states to the apps 141 and 143 via the context module 149 a. According to an embodiment of the disclosure, the processor 150 may, through the context module 149 a, receive (3) the context information from the apps 141 and 143 and send (4) to the intelligent agent 145.

According to an embodiment, the processor 150 may receive a plurality of context information from the apps 141 and 143 via the context module 149 a. The context information may be, e.g., information about the apps 141 and 143 executed latest. As another example, the context information may be information about the current states of the apps 141 and 143 (e.g., in the case a photo is viewed in a gallery, information about the photo).

According to an embodiment of the disclosure, the processor 150 may, through the context module 149 a, receive the context information indicating the current state of the user terminal 100 not only from the apps 141 and 143 but also from a device platform. The context information may include normal context information, user context information, or device context information.

The normal context information may include normal information about the user terminal 100. The normal context information may be identified by receiving data through, e.g., a sensor hub of the device platform, and by an internal algorithm. For example, the normal context information may include information about the current time/space. The information about the current time/space may include information about, e.g., the current time or the current position of the user terminal 100. The current time may be identified by the clock of the user terminal 100, and the information about the current position may be identified by the global positioning system (GPS). As another example, the normal context information may include information about physical motion. The information about physical motion may include information about, e.g., walking, running, or driving. The physical motion information may be identified by a motion sensor. The driving information may be identified by the motion sensor, and a Bluetooth connection in the vehicle may be detected so that getting aboard and parking may be identified. As another example, the normal context information may include user activity information. The user activity information may include information about, e.g., commuting, shopping, or traveling. The user activity information may be identified using information about the place which has been registered in the database by the user or app.

The user context information may include information about the user. For example, the user context information may include information about the user's emotional state. The emotional state information may include information about, e.g., the user's happiness, sadness, or anger. As another example, the user context information may include information about the user's current state. The current state information may include information about, e.g., interest or intent (e.g., shopping).

The device context information may include information about the state of the user terminal 100. For example, the device context information may include information about the path rule executed by the execution manager module 147. As another example, the device information may include battery information. The battery information may be identified through, e.g., the charged or discharged state of the battery. As another example, the device information may include information about the network or a connected device. The information about the connected device may be identified through the communication interface connected with the device.

According to an embodiment of the disclosure, the processor 150 may execute the hint providing module 149 c_1 which may provide hints to the user. For example, the processor 150 may, through the hint providing module 149 c_1, receive generated hints from the context hint generating module 149 c_2, the reuse hint generating module 149 c_5, or introduction hint generating module 149 c_6 and provide the hints to the user.

According to an embodiment of the disclosure, the processor 150 may execute the condition checking module 149 c_3 or the condition model module 149 c_4 to generate hits recommendable as per the current state. The processor 150 may execute the condition checking module 149 c_3 to receive information corresponding to the current state and execute the condition model module 149 c_4 to set a condition model using the received information. For example, the processor 150 may execute the condition model module 149 c_4 to identify, e.g., the time, location, context, or app being used, when the hints are provided to the user, and provide the user with the hints highly likely to be used in descending order of priority.

According to an embodiment of the disclosure, the processor 150 may execute the reuse hint generating module 149 c_5 to generate hints as per the use frequency. For example, the processor 150 may execute the reuse hint generating module 149 c_5 to generate hints based on the user's use pattern.

According to an embodiment of the disclosure, the introduction hint generating module 149 c_6 may generate hints to introduce the user to new functions or functions that other users frequently use. For example, a hint to introduce new functions may include an introduction to the intelligent agent 145 (e.g., a method to operate).

According to an embodiment of the disclosure, the context hint generating module 149 c_2, condition checking module 149 c_3, condition model module 149 c_4, reuse hint generating module 149 c_5, or introduction hint generating module 149 c_6 of the proposal module 149 c may be included in the personal information server 300. For example, the processor 150 may, through the hint providing module 149 c_1 of the proposal module 149 c, receive hints from the context hint generating module 149 c_2, reuse hint generating module 149 c_5, or introduction hint generating module 149 c_6 of the personal information server 300 and provide the received hints to the user.

According to an embodiment of the disclosure, the user terminal 100 may provide hints according to a series of processes as follows. For example, upon receiving a provide hint request from the intelligent agent 145, the processor 150 may transfer a generate hint request to the context hint generating module 149 c_2 through the hint providing module 149 c_1. Upon receiving the generate hint request, the processor 150 may, through the condition checking module 149 c_3, receive information corresponding to the current state from the context module 149 a and persona module 149 b. The processor 150 may transfer the received information to the condition model module 149 c_4 through the condition checking module 149 c_3 and may, the condition model module 149 c_4, assign priorities to the hints provided to the user in descending order of availability using the information. The processor 150 may, through the context hint generating module 149 c_2, identify (6) the condition and generate hints corresponding to the current state. The processor 150 may transfer the generated hints to the hint providing module 149 c_1 through the context hint generating module 149 c_2. The processor 150 may, through the hint providing module 149 c_1, sort the hints as per a designated rule and transfer the hints to the intelligent agent 145.

According to an embodiment of the disclosure, the processor 150 may, through the hint providing module 149 c_1, generate a plurality of context hints and assign priorities to the plurality of context hints as per a designated rule. According to an embodiment of the disclosure, the processor 150 may, through the hint providing module 149 c_1, first provide the user with the higher-priority ones among the plurality of context hints.

According to an embodiment of the disclosure, the user terminal 100 may propose hints as per use frequency. For example, upon receiving a provide hint request from the intelligent agent 145, the processor 150 may transfer a generate hint request to the reuse hint generating module 149 c_5 through the hint providing module 149 c_1. Upon receiving the generate hint request, the processor 150 may, through the reuse hint generating module 149 c_5, receive user information from the persona module 149 b. For example, the processor 150 may, through the reuse hint generating module 149 c_5, receive the path rule included in the user's preference information, parameters included in the path rule, frequency of execution of app, and information about the time/space where the app has been used, from the persona module 149 b. The processor 150 may generate hints corresponding to the received user information through the reuse hint generating module 149 c_5. The processor 150 may transfer the generated hints to the hint providing module 149 c_1 through the reuse hint generating module 149 c_5. The processor 150 may, through the hint providing module 149 c_1, sort the hints and transfer the hints to the intelligent agent 145.

According to an embodiment of the disclosure, the user terminal 100 may propose hints for new functions. For example, upon receiving a provide hint request from the intelligent agent 145, the processor 150 may transfer a generate hint request to the introduction hint generating module 149 c_6 through the hint providing module 149 c_1. The processor 150 may, through the introduction hint generating module 149 c_6, transfer a provide introduction hint request from a proposal server 400 and receive information about functions to be introduced from the proposal server 400. For example, the proposal server 400 may store the information about the functions to be introduced. A hint list for the functions to be introduced may be updated by the service operator. The processor 150 may transfer the generated hints to the hint providing module 149 c_1 through the introduction hint generating module 149 c_6. The processor 150 may, through the hint providing module 149 c_1, sort the hints and transmit (6) the hints to the intelligent agent 145.

Accordingly, the processor 150 may provide hints generated by the context hint generating module 149 c_2, reuse hint generating module 149 c_5, or introduction hint generating module 149 c_6 to the user through the proposal module 149 c. For example, the processor 150 may, through the proposal module 149 c, display the generated hints on the app that operates the intelligent agent 145 and receive inputs to select the hints from the user through the app.

FIG. 7 is a view illustrating a method for generating a path rule by a path planner module according to an embodiment of the disclosure.

Referring to FIG. 7, according to an embodiment of the disclosure, the NLU module 220 may sort functions of an app into any one operation (e.g., state A to state F) and store in the PR DB 231. For example, the NLU module 220 may store a path rule set including a plurality of path rules A-B1-C1, A-B1-C2, A-B1-C3-D-F, and A-B1-C3-D-E-F divided into any one operation in the PR DB 231.

According to an embodiment of the disclosure, the PR DB 231 of the path planner module 230 may store the path rule set to perform the functions of the app. The path rule set may include a plurality of path rules including the plurality of operations (e.g., a sequence of states). In the plurality of path rules, the operations executed as per the parameters each inputted to a respective one of the plurality of operations may sequentially be arranged. According to an embodiment of the disclosure, the plurality of path rules may be configured in the form of ontology or a graph model and stored in the PR DB 231.

According to an embodiment of the disclosure, the NLU module 220 may select the optimal one A-B1-C3-D-F of the plurality of path rules A-B1-C1, A-B1-C2, A-B1-C3-D-F, and A-B1-C3-D-E-F corresponding to the parameters and the intent of the user input.

According to an embodiment of the disclosure, the NLU module 220 may deliver the plurality of path rules to the user terminal 100 unless there is a path rule perfectly matching the user input. For example, the NLU module 220 may select the path rule (e.g., A-B1) partially corresponding to the user input. The NLU module 220 may select one or more path rules (e.g., A-B1-C1, A-B1-C2, A-B1-C3-D-F, A-B1-C3-D-E-F) including the path rule (e.g., A-B1) partially corresponding to the user input and deliver the same to the user terminal 100.

According to an embodiment of the disclosure, the NLU module 220 may select one of the plurality of path rules based on an additional input of the user terminal 100 and deliver the selected path rule to the user terminal 100. For example, the NLU module 220 may select one (e.g., A-B1-C3-D-F) among the plurality of path rules (e.g., A-B1-C1, A-B1-C2, A-B1-C3-D-F, A-B1-C3-D-E-F) as per an additional user input (e.g., an input to select C3) of the user terminal 100 and send the selected path rule to the user terminal 100.

According to an embodiment of the disclosure, the NLU module 220 may determine the user's intent and parameters corresponding to the additional user input (e.g., an input to select C3) to the user terminal 100 through the NLU module 220 and send the user's intent or parameters determined to the user terminal 100. The user terminal 100 may select one (e.g., A-B1-C3-D-F) among the plurality of path rules (e.g., A-B1-C1, A-B1-C2, A-B1-C3-D-F, A-B1-C3-D-E-F) based on the parameters or intent sent.

Accordingly, the user terminal 100 may complete the operations of the apps 141 and 143 by the selected path rule.

According to an embodiment of the disclosure, when a user input having insufficient information is received by the intelligent server 200, the NLU module 220 may generate a path rule partially corresponding to the received user input. For example, the NLU module 220 may send the partially corresponding path rule to the intelligent agent 145. The processor 150 may execute the intelligent agent 145 to receive the path rule and transfer the partially corresponding path rule to the execution manager module 147. The processor 150 may execute a first app 141 as per the path rule through the execution manager module 147. The processor 150 may, through the execution manager module 147, send information about the insufficient parameters to the intelligent agent 145 while executing the first app 141. The processor 150 may, through the intelligent agent 145, send a request for additional input to the user using the information about the insufficient parameters. Upon receiving an additional input from the user, the processor 150 may, through the intelligent agent 145, send the same to the intelligent server 200 for processing. The NLU module 220 may generate an added path rule based on the parameter information and intent of the additional user input and send the path rule to the intelligent agent 145. The processor 150 may, through the intelligent agent 145, send the path rule to the execution manager module 147 to execute a second app 143.

According to an embodiment of the disclosure, when a user input having some missing information is received by the intelligent server 200, the NLU module 220 may send a request for user information to the personal information server 300. The personal information server 300 may send, to the NLU module 220, information about the user who has entered the user input stored in the persona database. The NLU module 220 may select a path rule corresponding to the user input having some missing operations using the user information. Accordingly, although a user input having some missing information is received by the intelligent server 200, the NLU module 220 may send a request for the missing information and receive an additional input, or the NLU module 220 may use the user information, determining a path rule corresponding to the user input.

Table 1 below may represent an example path rule related to tasks requested by the user according to an embodiment.

TABLE 1 Path rule ID State parameter Gallery_101 pictureView(25) NULL searchView(26) NULL searchViewResult(27) Location, time SearchEmptySelectedView(28) NULL SearchSelectedView(29) ContentType, selectall CrossShare(30) Anaphora

Referring to Table 1, a path rule generated or selected by an intelligent server (e.g., the intelligent server 200 of FIG. 1) according to an utterance (e.g., “Share photos”) may include at least one state 25, 26, 27, 28, 29, or 30. For example, the at least one state (e.g., any one operation state of the terminal) may correspond to at least one of executing a photo application (PicturesView) 25, executing a photo search function (SearchView) 26, outputting a search result display screen (SearchViewResult) 27, outputting a search result display screen with no photo selected (SearchEmptySelectedView) 28, outputting a search result display screen with at least one photo selected (SearchSelectedView) 29, or outputting a shared application selection screen (CrossShare) 30.

According to an embodiment, the path rule parameter information may correspond to at least one state. For example, it may be included in the state 29 of outputting a search result display screen with at least one photo selected.

As a result of performing the path rule including the sequence of states 25, 26, 27, 28, 29, or 30, the task (e.g., “Share photos!”) requested by the user may be performed.

FIG. 8 is a view illustrating an example of managing user information by a persona module of an intelligent service module according to an embodiment of the disclosure.

Referring to FIG. 8, the processor 150 may receive information about the user terminal 100 from the apps 141 and 143, execution manager module 147, or the context module 149 a through the persona module 149 b. The processor 150 may, through the apps 141 and 143 and the execution manager module 147, store resultant information of execution of the app operations 141 b and 143 b in the operation log database. The processor 150 may, through the context module 149 a, store information about the current state of the user terminal 100 in the context database. The processor 150 may, through the persona module 149 b, receive the stored information from the operation log database or the context database. The data stored in the operation log database and the context database may be analyzed by, e.g., an analysis engine, and transferred to the persona module 149 b.

According to an embodiment of the disclosure, the processor 150 may, through the persona module 149 b, send the information received from the apps 141 and 143, the execution manager module 147, or the context module 149 a to the proposal module 149 c. For example, the processor 150 may, through the persona module 149 b, transfer the data stored in the operation log database or context database to the proposal module 149 c.

According to an embodiment of the disclosure, the processor 150 may, through the persona module 149 b, send the information received from the apps 141 and 143, the execution manager module 147, or the context module 149 a to the personal information server 300. For example, the processor 150 may, through the persona module 149 b, periodically send the data accrued in the operation log database or context database to the personal information server 300.

According to an embodiment, the processor 150 may, through the persona module 149 b, transfer the data stored in the operation log database or context database to the proposal module 149 c. User information generated by the persona module 149 b may be stored in a persona database. The persona module 149 b may periodically send user information stored in the persona database to the personal information server 300. According to an embodiment of the disclosure, the information sent by the persona module 149 b to the personal information server 300 may be stored in the persona database. The personal information server 300 may infer user information necessary to generate a path rule of the intelligent server 200 using the information stored in the persona database.

According to an embodiment of the disclosure, the user information inferred using the information sent from the persona module 149 b may include profile information or preference information. The profile information or the preference information may be inferred through the user's account and accrued information.

The profile information may include the user's personal information. The profile information may include, e.g., the user's population statistics information. The population statistics information may include, e.g., the user's gender or age. As another example, the profile information may include life event information. The life event information may be inferred by comparing log information with a life event model, and reinforced by analyzing the behavior pattern. As another example, the profile information may include interest information. The interest information may include, e.g., shopping goods of interest or field of interest (e.g., sports or politics). For example, the profile information may include activity region information. The activity region information may include information about, e.g., a home or workplace. The activity region information may include not only information about place or location but also information about regions recorded with priorities based on the accrued time of stay and visit count. For example, the profile information may include activity time information. The activity time information may include information about, e.g., wake-up time, commute time, or sleep time. The commute time information may be inferred using the activity region information (e.g., information about a home or workplace). The sleep time information may be inferred through unused time of the user terminal 100.

The preference information may include information about the user's preference. For example, the preference information may include information about an app preference. The app preference may be inferred through, e.g., record of use of an app (e.g., use record per time or place). The app preference may be used to determine an app to be executed as per the user's current state (e.g., time or place). For example, the preference information may include information about contacts preference. The contacts preference may be inferred by analyzing, e.g., information about how frequent one has contact with another, e.g., per time or place. The contacts preference may be used to determine contacts as per the user's current state (e.g., contact to overlapping names). As another example, the preference information may include setting information. The setting information may be inferred by, e.g., analyzing how frequent particular settings are made, e.g., per time or place. The setting information may be used to make particular settings as per the user's current state (e.g., time, place, or context). For example, the preference information may include place preference. The place preference may be inferred through, e.g., a record of visits to a particular place (e.g., a record of visit per time). The place preference may be used to determine the place that the user is visiting as per the user's current state (e.g., time). For example, the preference information may include command preference. The command preference may be inferred through, e.g., frequency of use of commands (e.g., use frequency per time or place). The command preference may be used to determine a command pattern to be used as per the user's current state (e.g., time or place). In particular, the command preference may include information about the menu chosen mostly by the user in the current state of the app executed through analysis of log information.

According to an embodiment, the intelligent agent 145 of the user terminal 100 may identify entry of a wake-up command (e.g., a wake-up utterance) while the call event occurs in operation 1420. For example, the wake-up utterance may be constituted of designated words (e.g., “Bixby!”).

According to an embodiment, the intelligent agent 145 may identify that the wake-up utterance is entered by identifying selection of a designated button (e.g., the hardware key 112) of the user terminal 100 or a button of an external electronic device (e.g., a wired or wireless earphone) wired or wirelessly connected with the user terminal 100.

According to an embodiment, the intelligent agent 145 may send a request for context information of the phone application to the dialer 1253 in operation 1430.

According to an embodiment, the dialer 1253 may transmit phone application context information related to the occurring call event to the intelligent agent 145 in operation 1440.

According to an embodiment, the intelligent server 200 may identify a first feedback for utterance based on the transmitted phone application context information in operation 1450 and transmit data of the first feedback for utterance to the intelligent agent 145 in operation 1460. For example, the first feedback may include information about the call event and information inquiring whether to perform an operation subsequent to the event.

According to an embodiment, the intelligent agent 145 may output the feedback in various forms through the input/output device 340 (e.g., a speaker or display) of the user terminal 100 in operation 1461. For example, the feedback may include the content “You have a call from your colleague, Suzie,” as the call event-related information and the content “You want to take the call?” as the information inquiring whether to perform the subsequent operation.

According to an embodiment, the intelligent agent 145 may identify the user's response to the first feedback and transmit the user's response to the intelligent server 200 in operation 1470.

According to an embodiment, the intelligent server 200 may send a request for a task of the phone application executable depending on the user's response to the intelligent agent 145 in operation 1480. For example, when a negative user response for the first feedback is entered or no response is received within a designated time, the intelligent server 200 may send a request for a task of the phone application executable on the dialer 1253 as the additional operation to the call event.

According to an embodiment, the intelligent agent 145 may transfer the task request to the dialer 1253 in operation 1481.

According to an embodiment, the dialer 1253 may identify a task according to the user's response and transmit the identified task to the intelligent server 200 in operation 1482.

According to an embodiment, the intelligent server 200 may identify a second feedback for the utterance based on the identified task and transmit it to the intelligent agent 145 in operation 1490. For example, the second feedback may include information inquiring whether to execute the identified task.

According to an embodiment, as the user enters a negative response to the utterance, e.g., not taking the call, for the occurring call event, the intelligent server 200 may identify, as the second feedback, the operation of transmitting a message to notify the caller that the call may not be taken, which corresponds to the subsequent operation of the utterance.

According to an embodiment, the intelligent agent 145 may output the second feedback received from the intelligent server 200 through the input/output device 340 in operation 1491. For example, the second feedback may include the content “Do you want to send Suzie a message to indicate that you are driving?” to inquire whether to send a message to the caller.

According to an embodiment, when an utterance is entered while an event for an application occurs, the user terminal 100 may output, as feedback, information inquiring whether to perform the operation of the application where the event occurs in relation to the utterance. Selectively, the user terminal 100 may receive a user input for the feedback and output information inquiring whether to additionally perform an operation of the application. For example, the user may identify the occurring event on the application through the intelligence system and receive feedback inquiring whether to perform the event-related operation.

FIG. 15 is a block diagram illustrating example components of an intelligence system and example operations among the components according to an embodiment of the disclosure.

Referring to FIG. 15, an intelligence system may include an intelligent server 200 and a user terminal 100. The intelligent server 200 may include an ASR module 210, an NLU module 220, and a TTS module 260, and the user terminal 100 may include an intelligent agent 145, an execution manager module 147, and an alarm application 1560 b (or, an ‘alarm’).

According to an embodiment, the alarm 1560 b may identify that an alarm event occurs in operation 1510. For example, when the alarm event occurs, the alarm 1560 b may output information to indicate that the current time has reached a particular date and time or that a designated schedule is coming up in various types of data, e.g., speech, image, or text data.

According to an embodiment, the intelligent agent 145 may identify entry of a wake-up command (or wake-up utterance) from the user while the alarm event occurs in operation 1520. For example, the wake-up utterance may be constituted only of designated words.

According to an embodiment, the intelligent agent 145 may determine whether an additional utterance is entered within a predetermined time after the utterance has been entered in operation 1521. For example, when an additional utterance is entered within the designated time, an operation of an application of the user terminal 100 corresponding to the additional utterance may be performed.

According to an embodiment, upon determining that no additional utterance is entered within the designated time, the intelligent agent 145 may control the execution manager module 147 to send a request for context information of an alarm application to the alarm 1560 b in operation 1530.

According to an embodiment, the alarm 1560 b may identify the context information of the alarm application and transfer to the execution manager module 147 in operation 1531.

According to an embodiment, the execution manager module 147 may transmit the context information to the intelligent server 200. For example, the NLU module 220 may select a first feedback for the utterance based on the context information in operation 1540 and transmit the selected first feedback to the user terminal 100 through the TTS module 260 in operation 1544.

According to an embodiment, the intelligent agent 145 may output the first feedback for the utterance in operation 1550.

According to an embodiment, the intelligent agent 145 may identify a user input for the first feedback in operation 1551. For example, the intelligent agent 145 may determine whether the user input indicates a positive or negative response to the first feedback or is received within a designated time.

According to an embodiment, the intelligent agent 145 may transfer the user input to the first feedback to the alarm 1560 b in operation 1560.

According to an embodiment, the alarm 1560 b may identify second context information according to task information as per the user input for the first feedback and transfer it to the intelligent agent 145 in operation 1561. For example, when the user input indicates a negative response or is not received within a designated time, the alarm 1560 b may identify second context information based on task flow (1563 a) information in the alarm 1560 b.

According to an embodiment, in operation 1562, the intelligent agent 145 may transmit the second context information to the ASR module 210 of the intelligent server 200 and reperform operations 1540 and 1544, selecting the second feedback for the utterance based on the second context information through the NLU module 220 and transmitting the selected feedback to the user terminal 100 through the TTS module 260.

According to an embodiment, the task flow 1563 a may include information about an operation flow when an event occurs in the alarm 1560 b, and information inquiring whether to perform a particular operation of the operation flow may be output as feedback. For example, the alarm 1560 b may include a task flow including the operations of going off, turning off, or snoozing an alarm when an alarm event occurs.

According to an embodiment, the intelligent agent 145 may output the second feedback through an input/output device (e.g., the display 120 or speaker 130 of FIG. 2) of the user terminal 100 in operation 1570.

FIG. 16 is a view illustrating an example screen configuration of setting an application to use an intelligent service according to an embodiment of the disclosure.

Referring to FIG. 16, a user terminal 100 may display a screen 1601 to set up whether to support feedback depending on the execution state in using an intelligent service. The screen 1601 may be displayed when a particular menu item of an application is selected or otherwise when a designated input is received.

According to an embodiment, the screen 1601 may display a list of applications and a function setting button 1611 for each application. The list of applications may include a phone application (call) 1610, a music play application (music), an alarm application (alarm), an instant messaging application (IM or K-talk), a short message service/multimedia messaging service (MMS) application (message), or a video play application (video) or other various applications stored in the user terminal 100.

According to an embodiment, when an input on a button 1611 corresponding to the ‘call’ 1610 is received, the button 1611 may be moved, e.g., right, and be set to ‘on.’ In this case, feedback for an entered utterance may be output based on the execution state of the alarm application. For example, when a wake-up utterance is entered while a call event occurs in the phone application, feedback for the entered utterance may be output including the caller information included in the call event or information inquiring whether to perform a subsequent operation (e.g., call reception).

According to an embodiment, when the ‘call’ 1610 item of the application list is selected, the screen 1601 may switch into a screen 1602 to select a detailed feedback type of ‘call.’ For example, the screen 1602 may include a selection item (e.g., 1621 a) to select feedback to be output and the type of feedback.

According to an embodiment, types of feedback may include a first feedback (information feedback) 1621 (e.g., “You have a call.”) including information about the event, a second feedback (next or subsequent task feedback) 1622 (e.g., “Do you want to take the call?”) including information about a task performable as an operation subsequent to the event, or a third feedback (progress feedback) 1623 (e.g., “Phone has rung three times.”) including information related to the progress of the event For example, when the user selects the selection item 1621 a for the first feedback 1621, and an utterance is entered while a call event occurs in the phone application, feedback containing information about the call event may be output as feedback for the utterance.

FIGS. 17A, 17B, and 17C are views illustrating various example scenarios of outputting feedback by an electronic device according to entry of a user's utterance in an intelligence system according to an embodiment of the disclosure.

Referring to FIG. 17A, an alarm event may be occurring from an alarm application (e.g., the alarm 1560 b) in a user terminal 100. The user 1301 may enter a wake-up utterance (e.g., “Bixby!”) to the user terminal 100 while the alarm event occurs.

According to an embodiment, when there is no additional utterance within a designated time after the utterance has been entered, the user terminal 100 may identify context information (app context info.) of the alarm application where the event occurs. The context information of the alarm application may include a current task, a subsequent task, or feedback type (speech feedback type). For example, the user terminal 100 may identify the current task as alarm ringing, the subsequent task as an alarm end task as an operation performable as an operation subsequent to the current task, and the feedback type as feedback including information inquiring whether to perform the ‘next task’ as the subsequent task is identified.

According to an embodiment, the user terminal 100 may output feedback for the utterance depending on the feedback type. For example, the user terminal 100 may output the feedback including information (e.g., “Do you want to turn off the alarm?”) inquiring whether to end the alarm as the task subsequent to the alarm ringing operation which is the current task.

According to an embodiment, the user may activate the intelligence system using a brief word and not only identify the operation subsequent to the currently occurring event but also determine whether to perform.

Referring to FIG. 17B, a call event may occur from a phone application (e.g., the dialer 1253) in the user terminal 100. The user 1701 may enter a wake-up utterance (e.g., “Bixby!”) to the user terminal 100 while the call event occurs.

According to an embodiment, when there is no additional utterance within a designated time after the utterance has been entered, the user terminal 100 may identify context information of the phone application where the event occurs. The current task of the phone application may be identified as call receiving (call ringing), and the feedback type may be identified as feedback including information about the current task.

According to an embodiment, the user terminal 100 may output information about the current task executed on the phone application as feedback for the utterance depending on the feedback type. For example, the user terminal 100 may output, as the feedback for the utterance, feedback including the content “You have a call from Suzie.”

According to an embodiment, the user terminal 100 may additionally identify a task subsequent to the current task or output feedback including information inquiring whether to perform the subsequent task and the information about the current task depending on the feedback settings for the phone application. For example, as the user terminal 100 identifies the operation of taking the received call as the subsequent task to the current task of call receiving, the feedback for the utterance may include the content “You have a call from Suzie. Do you want to take the call?”

According to an embodiment, the user may activate the intelligence system using a brief word and receive, as feedback, information about the currently occurring event and information inquiring whether to perform the subsequent operation.

Referring to FIG. 17C, a music download event may occur from a music play application (e.g., the media player 382) in the user terminal 100. The user 1701 may enter a wake-up utterance (e.g., “Bixby!”) to the user terminal 100 while the music download event occurs.

According to an embodiment, when there is no additional utterance within a designated time after the utterance has been entered, the user terminal 100 may identify context information of the music play application where the event occurs. For example, by identifying music downloading as the current task of the music play application, the user terminal 100 may identify the feedback type as outputting progress indicating information.

According to an embodiment, the user terminal 100 may output, as feedback for the utterance, information about the music downloading task executed on the music play application. For example, the user terminal 100 may output feedback containing the content “music downloading 10% complete” as the feedback for the utterance.

According to an embodiment, as the user terminal 100 identifies information (e.g., musician or song title) about the content where an event occurs, the user terminal 100 may output, as feedback, information about the content, along with information indicating the progress of the current task. For example, the feedback for the utterance may include the content “Song by musician (e.g., TEE, Bye′) titled (Yawn) is downloading. 10% complete.”

According to an embodiment, the user may activate the intelligence system using a brief word and receive, as feedback, information about the currently occurring event and the progress.

FIG. 18 is a view illustrating an example scenario of outputting feedback from a smart speaker according to entry of an utterance in an intelligence system according to an embodiment of the disclosure.

Referring to FIG. 18, an intelligence system may include a smart speaker (or AI speaker) 1803, an intelligent service server 1804, or an intelligent server 200.

According to an embodiment, a user 1801 may enter a wake-up utterance to the smart speaker 1803. For example, the smart speaker 1803 may be a device connected with the intelligent server 200 to output feedback for an utterance received in the form of a speech.

According to an embodiment, an intelligent agent (e.g., the intelligent agent 145) of the smart speaker 1803 may identify that the wake-up utterance has been entered as it identifies selection of a designated button (e.g., the hardware key 112) of the smart speaker 1803.

According to an embodiment, the smart speaker 1803 may transfer the received utterance to the intelligent service server 1804 that supports an AI service platform for providing services through the smart speaker 1803. For example, the intelligent service server 1804 may identify whether a subsequent utterance comes in within a designated time.

According to an embodiment, although the smart speaker 1803 has been described to transfer the received utterance to the intelligent service server 1804, the intelligent service server 1804 may be omitted or, when not connected with the smart speaker 1803, the utterance may be transferred to the intelligent server 200.

According to an embodiment, when no utterance subsequent to the received utterance is identified, the intelligent server 200 or the intelligent service server 1804 may identify feedback based on the service being currently executed on the smart speaker 1803 and the feedback may be transferred to the smart speaker 1803.

According to an embodiment, when the user 1801 issues an utterance, saying “Order a kitchen towel,” along with a wake-up utterance (e.g., “Bixby˜”), the intelligent server 200 or the intelligent service server 1804 may interpret the utterance of the user 1801 and perform an operation for ordering a ‘kitchen towel.’ For example, the intelligent server 200 or the intelligent service server 1804 may transfer a result of performing the operation to the smart speaker 1803 so that the result may be outputted through the smart speaker 1803 in the form of a speech.

According to an embodiment, when no feedback for the received utterance is output, such as when communication between the intelligent server 200 or the intelligent service server 1804 and the smart speaker 1803 is delayed, the user 1801 may reenter a wake-up utterance. For example, the intelligent server 200 or the intelligent service server 1804 may transfer feedback for the reentered wake-up utterance including information about the received utterance to the smart speaker 1803. For example, the feedback for the reentered wake-up utterance may include information about the progress (e.g., “A search is now in progress.”) or information about a subsequent task (e.g., “Do you want to stop searching?”) for the received utterance.

According to an embodiment, the user 1801 may play music as a streaming service through the smart speaker 1803. For example, when the user 1801 enters a wake-up utterance during a streaming service, the intelligent server 200 or the intelligent service server 1804 may identify information related to the streaming service as feedback for the wake-up utterance.

According to an embodiment, when the smart speaker 1803 temporarily drops out while playing music or connection with the server providing the streaming service is unstable, the user 1801 may enter a wake-up utterance (e.g., “Bixby˜”) to the smart speaker 1803. For example, the intelligent server 200 or the intelligent service server 1804 may identify information related to the streaming service being executed on the smart speaker 1803 as feedback for the wake-up utterance. The streaming service-related information may include at least part of connection state information of the streaming service (e.g., “Music downloading is currently delayed due to network latency.”), subsequent task information (e.g., “Do you want to play the downloaded music?” or “Do you want to play music via another music streaming service?”), or the state of the streaming service (e.g., “Slow response from the server (e.g., intelligent service server 1804)”).

According to an embodiment, while playing a song on the streaming service, the user 1801 may enter an utterance (e.g., “Save (or purchase) the song now in play.”) to store the song in the memory of the smart speaker 1803 or purchase the song, along with a wake-up utterance (e.g., “Bixby˜”), to the smart speaker 1803. For example, while a certain song is being downloaded based on the utterance, the user may enter a wake-up utterance to identify the state of the download. For example, the smart speaker 1803 may output download state information (e.g., “Currently 30% downloaded. The remaining time is 3 seconds.”) as feedback for the wake-up utterance.

According to an embodiment, when the user enters a wake-up utterance through various electronic devices connected with the intelligent server 200, feedback containing operation state information or subsequent task information may be output based on a function executed on a corresponding electronic device.

According to an embodiment, the antenna module 1997 may include one or more antennas, and, therefrom, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 1998 or the second network 1999, may be selected, for example, by the communication module 1990 (e.g., the wireless communication module 192). The signal or the power may then be transmitted or received between the communication module 1990 and the external electronic device via the selected at least one antenna.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 1901 and the external electronic device 1904 via the server 1908 coupled with the second network 1999. Each of the electronic devices 1902 and 104 may be a device of a same type as, or a different type, from the electronic device 1901.

According to an embodiment, all or some of operations to be executed by the electronic device 1901 may be executed at one or more of the external electronic devices 1902, 1904, or 1908. For example, if the electronic device 1901 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 1901, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 1901. The electronic device 1901 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.

The electronic device according to various embodiments may be one of various types of electronic devices. The electronic devices may include at least one of, e.g., a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or a home appliance. According to an embodiment of the disclosure, the electronic devices are not limited to those described above.

The same or similar reference denotations may be used to refer to the same or similar elements throughout the specification and the drawings. It is to be understood that the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. As used herein, the term “A or B,” “at least one of A and/or B,” “A, B, or C,” or “at least one of A, B, and/or C” may include all possible combinations of the enumerated items. As used herein, the terms “1st” or “first” and “2nd” or “second” may modify corresponding components regardless of importance and/or order and are used to distinguish a component from another without limiting the components. It will be understood that when an element (e.g., a first element) is referred to as being (operatively or communicatively) “coupled with/to,” or “connected with/to” another element (e.g., a second element), it can be coupled or connected with/to the other element directly or via a third element.

As used herein, the term “module” includes a unit configured in hardware, software, or firmware and may interchangeably be used with other terms, e.g., “logic,” “logic block,” “part,” or “circuit.” A module may be a single integral part or a minimum unit or part for performing one or more functions. For example, the module may be configured in an application-specific integrated circuit (ASIC).

Various embodiments as set forth herein may be implemented as software (e.g., the program 1940) containing commands that are stored in a machine (e.g., computer)-readable storage medium (e.g., an internal memory 1936) or an external memory 1938. The machine may be a device that may invoke a command stored in the storage medium and may be operated as per the invoked command. The machine may include an electronic device (e.g., the electronic device 101) according to embodiments disclosed herein. When the command is executed by a processor (e.g., the processor 150), the processor may perform a function corresponding to the command on its own or using other components under the control of the processor. The command may contain a code that is generated or executed by a compiler or an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, the term “non-transitory” simply means that the storage medium does not include a signal and is tangible, but this term does not differentiate between where data is semi-permanently stored in the storage medium and where data is temporarily stored in the storage medium.

According to an embodiment, a method according to various embodiments of the disclosure may be included and provided in a computer program product. The computer program products may be traded as commodities between sellers and buyers. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., a compact disc read only memory (CD-ROM)) or online through an application store (e.g., Playstore™). When distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in a storage medium, such as the manufacturer's server, a server of the application store, or a relay server.
